It’s been far too long….

Today it dawned on me that I haven’t done a solid post on anything anthropological or biomedical for a very long time. I also came across an old list I have tucked into one of my biology books. There’s no author on it nor where it came from so I can’t give anyone credit for putting it all together. There is a list of where the author got all these facts and I did include those links at the end. Just know I didn’t come up with any of these. Anything in [brackets] is the first thought that came in my head after I read the fact.

Amazing and Awesome Facts About the Human Body.

-Humans shed about 600,000 particles of skin every hour. In fact, most of the dust underneath your bed is probably your own dead skin. [I shed more then all my pets combined?]

-A human baby has 99 more bones than an adult. A baby’s skeleton is mostly made up of cartilage. As a person grows up, most of this cartilage turns into bone in a process called ossification, and the ossification process results in the joining of certain bones. Consequently, new born babies have around 305 bones, while an adult has just 206 bones. [How else would they painfully squeeze their way out of a woman’s body?]

-There are 100,000 miles of blood vessels in an adult human body. The largest blood vessel is the aorta, which is just over an inch in diameter. [I do not suggest measuring your blood vessels or aorta…..then again, if you cannot vanquish this urge, measure away!]

-In a lifetime, an average person produces about 25,000 quarts of saliva, enough to fill two swimming pools. We also produce about a litre of mucus per day. [Does raspberries make this count rise?]

-Your body has enough iron in it to forge a 3-inches-long nail. You also have enough sulfur to kill all fleas on an average dog, enough carbon to make 900 pencils, enough potassium to fire a toy cannon, enough fat to make 7 bars of soap, enough phosphorous to make 2,200 match heads, and enough water to fill a ten-gallon tank. [Now figure out how much all those things are worth and you’ve got the worth of a human being. Financially at least, human individuals sometimes aren’t worth a penny and they probably would have been worth the amount of a good condom.]

-We all have tiny mites living in our eyelashes. These little mites actually aren’t too choosey; they’ll live anywhere as long as they have access hair follicles. They’re found on other parts of the body and on a host of other mammals. [Strangely this doesn’t bother me]

-Pound for pound, the strongest muscle in the human body is the masseter (jaw muscle). It can clamp your chompers shut with 55 pounds of force on the incisors and 200 pounds of force on the molars. [Guess you need to stop telling people to bite you 80’s babies!]

-Sweat itself is odorless. It’s the bacteria on the skin that mingles with it and produces body odor. Bacteria that are naturally present on our skin thrive in sweaty regions. [Damn bacteria! Why must you always be victorious?]

-Your ears and nose will never stop growing until the day you die. In fact, your earlobes will also elongate from gravity. [Lie to me, tell me the truth….]

-Similar to fingerprints, everyone also has a unique tongue print. It may be some time before your local police station starts taking tongue prints, but research on the required 3-D imaging technology is already being developed and tested. [Good thing you don’t have to lick stamps any longer…]

-Ounce for ounce, human bones are stronger than steel. A cubic inch of bone can bear a load of 19,000 lbs.—roughly the weight of five pickup trucks. [Just don’t have five pickup trucks run you over…no guarantee you’ll be fine.]

-People with blue eyes have a higher alcohol tolerance. Interestingly, they also have higher rates of alcohol abuse and dependency. [I did have a high alcohol tolerance. But I stopped drinking when I turned 21.]

-If the human eye was a digital camera it would have 576 megapixels. Currently, the most expensive digital camera in the world has 200 megapixels. [I have lamented many a time how something I am looking at cannot be captured by a camera with the same brilliant look I can see. For example the damn moon.]

-All of the bacteria in our body collectively weighs about 4 pounds. That’s enough to fill a big soup can. In fact, there are more bacteria in your mouth than there are people in the world. [Four pounds of bacteria. FOUR POUNDS I NEED TO LOOSE!]

-In some cardiovascular units, slow and quiet music is used to relax the patients and lower their blood pressure and heart rate. [This is why people are calmer with slow quiet music and it’s most often found in mental health clinics and floors. The opposite is also true. Loud, quick music makes us energetic.]

-Your brain accounts for only 2% of your body weight, yet it uses 20% of the total oxygen and blood in your body. [What an o2 hog!]

-If uncoiled, the DNA in all of your body’s cells would stretch 10 billion miles, which is long enough to reach from here to Pluto and back. [You’d also die]

-Within three days of death, the enzymes that once digested your dinner begin to eat you. Ruptured cells will become food for the bacteria in your gut, which will release enough noxious gas to bloat your body and force your eyes to bulge outward. [Body Farm anyone?]

-In a lifetime, your brain’s long-term memory can hold up to 1 quadrillion (1 million billion) bits of information. [But apparently we don’t always have access to any of it when we could really use it]

-Your heart will pump about 1.5 million barrels of blood during your lifetime. That’s enough to fill 200 train tank cars. [Best not to try this at home]

-As long as it has an oxygen supply, your heart can keep beating even if it’s separated from the body because it has its own electrical impulse. [In case you ever thought that scene in Indiana Jones and the Temple of Doom couldn’t happen]

-Your brain keeps developing until your late 40s. [Learn, learn and learn some more!]

-Human fingers can feel objects as small as 13 nanometers. This means that if your finger was the size of the Earth, you would feel the difference between houses and cars. [Brings a whole new level to ‘Your momma’ jokes..]

-The highest recorded body temperature in a human being was a fever of 115.7°F. A fever over 107.5°F is enough to damage the brain and, if untreated, cause death. [♪♫ You give me fever♬♩♫]

-The human heart is not on the left-hand side of the body. It’s in middle of your chest, in between your right and left lung. It is, however, tilted very slightly to the left. [In 6th grade we were taught that it was on the left side. And that blood is blue until it hit oxygen then it turns red. ‘(◣_◢)’ ]

-Half of your genes describe the complex design of your brain, with the other half describing the organization of the other 98% of your body. [This must mean that some people have only 10% of their genes describing the complex design of their brain and 90% describing the organization of the other 98% of the body.]

-Your taste buds are replaced every 10 days. Conversely, the average age of a human fat cell is 10 years. [I wish 80% of them would die already].

-There is no scientific evidence that shaving or waxing will make your hair come back thicker. There are believed to be two reasons that the myth continues to flourish. First, humans just aren’t the best observers. Second, hair often does grow back thicker when people first start to shave, but this isn’t caused by shaving. When an adolescent boy shaves his mustache for the first time, it’s likely to grow back thicker. This isn’t because shaving caused this; it’s because the hormonal changes in his body (which occur regardless of shaving) are encouraging new and thicker facial hair growth.

-1 in 10,000 people has their internal organs reversed or “mirrored” from their normal positions. The condition is called situs inversus. [I have a rare one in a million skin thing that pops up every so often that I was diagnosed with in middle school of whose name I can’t remember as I haven’t had problems with it until possibly recently. Also, would a doctor think about this condition when they can’t find a patient’s organ or freak the hell out?]

-Without your pinky finger, you would lose about 50% of your hand strength. While the index and middle fingers function with the thumb in pinching and grabbing, it’s the pinkie that teams up with the ring finger to provide grip power. [Pinkie Power! ᕦ(ò_óˇ)ᕤ]

-Men’s Testicles hang between the legs to keep cool because sperm dies at body temperature. Keeping those baby-makers cool is a top priority, so make sure to keep your laptop off those bad boys! [And depending on some factors you may want to keep that laptop and other hot things ON those bad boys]

-1 person out of every 200 people has an extra rib. [And women actually do have the same number of ribs as men. The myth that says men have more is from a work of fiction]

-Your mouth is made of the same skin cells as a vagina. Flattened epithelial cells are well suited to areas in the body subject to constant abrasion, as layers can be sloughed off and replaced quickly. [How do you think some women get Angelina Jolie lips??]

-Muscle comes from the Latin “musculus.” Musculus means “little mouse,” and this was used to describe muscles because biceps were thought to look like mice. [*flexes bicep* Mine looks like, well, not a cute mouse that’s for sure!]

-When telling a lie, people blink less frequently than normal. After the lie is told, they speed up to around eight times faster than usual. [Now knowing this is going to make you quite self aware for a bit whether you are lying or not]

-More than 3% of people are born with phonagnosia: they can’t recognize the voices of familiar people. People suffering from phonagnosia do not suffer from aphasia (an inability to comprehend and formulate language), which suggests that separate areas of the brain govern linguistic comprehension and voice recognition. [I once thought I heard my husband’s voice at a gas station when he was in Germany. For a moment I thought he had come home early. So disappointed.]

-A scientist cracked his knuckles on one hand for over 50 years to prove it did not cause Arthritis. After 50 years, he concluded that there was no arthritis in either hand, and no apparent differences between the two hands. This is, of course, a rather small data set, but it’s interesting none the less! [I used to crack them, but I got bored with it so stopped for the most part.]

-You can burn 20% more fat by exercising in the morning on an empty stomach. Sex burns 3.6 calories a minute, so fifteen minutes of morning sex should burn off 130 calories. [Take THAT to the bedroom!]

-Humans have no more genes than worms. We have less genes than a tomato. How could this be, given that the all-powerful homo sapiens are clearly a more complex species? We’re not sure, but scientist have noted that the number of genes in the genome may be less linked to complexity than we thought. [Gives new meaning to being as smart as a tomato.]

-A strong cough forces air out of the airways at speeds up to 620 mph, which is almost as fast as the speed of sound. [Never mind the pain in the ribs at repeated coughs]

-Hearing is the fastest human sense. Your brain can recognize a sound 10 times faster than the blink of an eye, in as little as 0.05 seconds. [I was told I have better hearing than most people. This isn’t always a good thing as I am annoyed by more sounds then normal people. And it’s usually the normal people that are making those sounds.]

-Bras make breasts sag. Bras also do not reduce back pain. A leading study found that women who never wore bras had nipples an average of seven millimeters higher each year than regular bra users. Before you go throwing away your bras, note that the benefits of not wearing a bra will only be seen in younger women who are not obese, according to those managing the study. [I feel sadness for the millions of women who moan and complain about their bras hurting them. Bras shouldn’t hurt. Stop buying them from Walmart! Get your tits to a lingerie store and get fitted for a bra that isn’t going to hurt you, you won’t even feel it’s there and you may just forget to take it off! It’s what I did and although I paid a higher price for the bras, they also lasted longer and made my girls happy. Always get more than two good fitting bras and rotate them daily, hand wash them, let them dry on a flat surface (NEVER hang them to dry, stretches them out) and store them in a familiar fashion instead of inverting one cup into the other. Happy breasts are sexy breasts ( o ) ( o ) ]

-After child birth, a woman’s vaginal muscles can take up to 6 months to get back to their normal shape and size. [Probably takes that long for her to want to open her legs up again]

-We can’t digest grass because our bodies don’t have what it takes to break down the cellulose found in the plant. Grass also contains a lot of silica, an abrasive that quickly wears down teeth, so your dentist wouldn’t be thrilled about a grass diet. Grazing animals have teeth that continually grow to replace worn tooth surfaces. [Can this be used against vegetarian (or as I like to call them ‘bad hunter’) diets?]

-Your big toe carries more weight than any other toe, bearing about 40% of your body weight. To enlist in the United States army, you need to have all ten toes intact. [New meaning to going toe to toe?]

-One prevailing theory as to why butt hair exists is that there’s simply no significant evolutionary pressure against butt hair. I.e. it doesn’t affect our ability to mate, so the random mutations that caused butt hair persisted.

Other theories take a smellier view of things, suggesting that butt hair helps scent communication. We have body hair in the same areas where we produce odors. The hair is there to hold onto oily secretions that have their own smell and are consumed by bacteria that produces even more smells. Early human ancestors used their personal smell to actually help them with everything from broadcasting territorial rights to attracting mates. [Wait, I have butt hair!!! (__(__)]
